Intel Updates Advanced Performance Extensions "APX" Code For The Linux Kernel

3 hodiny 38 min zpět
In addition to Intel software engineers this week being busy doing a late restructuring of AVX10 support in moving away from possible 256-bit maximum vector register size (a great move and still so excited to see this materialize!), there are also Intel engineers continuing work on enabling Advanced Performance Extensions (APX) on the Linux kernel side...

Mesa RADV vs. AMDVLK Vulkan Driver Performance For The AMD Radeon RX 9070 Series

20. Březen 2025 - 15:30
With my launch day testing of the Radeon RX 9070 graphics cards on Linux the Mesa RADV driver was used given that is what is predominantly used by Linux gamers/enthusiasts and is used out-of-the-box by all of the major Linux distributions. Last week AMD released an AMDVLK Vulkan driver with RDNA4 GPU support as the company's official open-source Vulkan API Linux driver. For those curious how the Mesa RADV and AMDVLK drivers are competing for the Radeon RX 9070 series, this article is for you with benchmarks of both drivers and both RX 9070 graphics cards.

Intel Wrapping Up Family 18 / Family 19 CPU Model Preparations Ahead Of Linux 6.15

19. Březen 2025 - 15:20
Over the past year Intel has been working to prepare the Linux kernel for the end of the "Family 6" CPU era. There's been a big rework to the Intel CPU model handling within the Linux kernel given that "Family 6" has been in use since the 1990s and moving forward Intel CPUs will appear in Family 19 like Diamond Rapids along with Family 18 as part of the new CPU identification. Thus a lot of Linux kernel checks need to be reconfigured for the multi-family Intel handling. With Linux 6.15 it looks like most of that will be finally wrapped up...

Beyond The ROCm Software, AMD Has Been Making Great Strides In Documentation & Robust Containers

19. Březen 2025 - 13:56
AMD recently allowed me some time with their AMD Accelerator Cloud (AAC) leveraging multiple Instinct MI300X accelerators. During this brief opportunity to try out their latest software advancements with the Instinct MI300X and the ROCm compute stack, one of the most striking takeaways was their documentation improvements compared to previous forays into ROCm+Instinct compute. In addition, AMD is now offering more robust container options for easier Instinct compute deployments with more software options available and being more regularly updated.

Intel AVX10 Drops Optional 512-bit: No AVX10 256-bit Only E-Cores In The Future

19. Březen 2025 - 11:48
Intel updated their AVX10 whitepaper and associated open-source compiler patches around this next Advanced Vector Extensions standard... While AVX10 had intended to allow either 256-bit or 512-bit modes depending upon processor capabilities, Intel has dropped the 256-bit-only approach and going for 512-bit everywhere. Thus it would seem to indicate that Intel E cores of the future will properly support AVX 512-bit operation!..
